For reference: These are black cherry tomatoes that are planted in a 7 gallon fabric pot and get around 8 hours of direct sunlight a day.
I'm concerned about potentially overwatering my tomato – we've been getting 30-40C degree weather recently (86-104F) and I've been watering them everyday.
The thing is, the soil is still slightly damp by the time I water (late afternoon/evening) and if I hold off watering for a day, the plant wilts quite badly the day after. If I do water anyway, some of the leaves curl a bit directly after, then go back to normal the next day – although the curl might be due to cooler nighttime temperatures. As of yesterday, however, the top pair of leaves in the photo aren't uncurling.

Also adding that I water until it runs out the bottom of the pot, and that the sticky traps are from fungus gnats spreading from some of my indoor plants!
The leaf curl is most likely from the hot temperatures. Sometimes at least in my experience some leaves don’t uncurl but still function normally. If it’s 40c I personally would water especially if they are in pots.
Do the finger test. If muddy then, Yes. If damp, Fine. If dry, Add.
Shade cloth for mid day sun and set a morning and evening light water. Hope that helps I live in a high desert so summer is very harsh sun.
